Speed limits are not suggestions

Re. “Edmonton, it’s time to end cash grab of photo radar,” David Staples, Oct. 4

David Staples’ contention is that the use of technology to detect and convict speeders is somehow sneaky and underhanded. This seems to be predicated on the notion that drivers can safely negotiate city streets by travelling 10 km/h over the speed limit. First, it is abjectly false. Speed limits are set using hard data and take into consideration variables including road and weather conditions, vehicle-stopping characteristics and the range of driver experience and abilities. They allow all drivers to maintain a critical margin of safety.

Speed is a causal factor in most motor vehicle accidents. If a driver is travelling over the speed limit they are voluntarily reducing the time and space within which they can react to an emergent event. Combine this with the too-common practices of following too closely and distracted driving, and you have a cocktail for disaster.

Secondly, if we tacitly allow 10 km/h over the speed limit, where will this end? Will 15, 20 and even 30 eventually be considered within the bounds of acceptable?

Speed limits are the law. They’re not suggestions. They are the tools law enforcement and our judicial system use to keep our streets safe.
